Amateur community in computer science (open source) and DIY for the construction of fisheye type projectors for often mobile planetariums. Initiated by Jean-Yves Lhoumeau and Lionel Ruiz. This community develops from the software "Stellarium" which became "Stellarium 360" then "SpaceCrafter".

The American manufacturer "Digitalis Educations" derived its software "Nightshade" from Stellarium.

The Spanish (Catalan) manufacturer "Immersive Adventure" offers a "turnkey" version of the LSS.
